9.  The applicant is a Netherlands national, born in 1953 and living in The Hague. He has been a practising lawyer (advocaat) since 1979.
10.  At the beginning of November 1993, the applicant agreed to act as defence counsel for a Mr K. in criminal proceedings brought against the latter. At that time, Mr K. was in pre-trial detention. In connection with this case, the applicant met several times with Mrs S., who at that time was Mr K.'s wife.
11.  At some point Mrs S. told Mr K. that on 9 November 1993 the applicant had made sexual advances towards her. Mr K. informed the police officer investigating his case, Officer N., of this, who in turn informed the public prosecutor in charge of the investigation against Mr K., Public Prosecutor T. The latter gave instructions that a criminal complaint against the applicant should be filed with the vice squad. On this basis, Officer N. contacted both Mrs S. and Officer R. of the vice squad.
12.  Mrs S. was initially reluctant to lodge a criminal complaint against the applicant as she feared that her word – the only evidence available – would be insufficient against that of the applicant.
13.  Following discussions between Officers R. and R.K. of the vice squad and Public Prosecutor T., the suggestion was made to Mrs S. to connect a tape recorder to her telephone in order to allow her to tape incoming conversations with the applicant. Police officers subsequently connected a cassette tape recorder to Mrs S.'s telephone in her home and suggested that she steer her conversations with the applicant towards the latter's advances. Mrs S. was shown how to operate the device. The police came to her home twice in order to collect the recordings and load new cassette tapes into the tape recorder.
14.  Mrs S. recorded three conversations with the applicant, which were transcribed by the police. These transcripts were added to the case-file on the investigation against the applicant.
15.  The case was reported in the press. This induced two other women to come forward and lodge criminal complaints against the applicant: one Mrs V., who claimed to have been raped and sexually assaulted by the applicant, and one Mrs C., who also complained that she had been sexually assaulted by the applicant.
16.  The applicant was subsequently summoned to appear on 14 April 1994 before the Regional Court (arrondissementsrechtbank) of The Hague on charges of sexual assault and rape.
17.  In its judgment of 28 April 1994, following adversarial proceedings in the course of which a hearing was held on 14 April 1994, the Regional Court convicted the applicant of having sexually assaulted Mrs S. and Mrs C., and acquitted him of the charges brought in respect of Mrs V. The Regional Court sentenced the applicant to eight months' imprisonment, four months of which were suspended for a probationary period of two years.
18.  Both the applicant and the public prosecutor lodged an appeal with the Court of Appeal (gerechtshof) of The Hague.
19.  In its judgment of 16 June 1995, the Court of Appeal quashed the judgment of 28 April 1994, convicted the applicant of having sexually assaulted Mrs S. and Mrs C. and acquitted him of the charges in respect of Mrs V. It sentenced the applicant to four months' imprisonment, suspended for a probationary period of two years, and a fine of 10,000 Netherlands guilders. It based the applicant's conviction on statements taken from the applicant, Mrs S., Mrs C. and three other persons. The recorded telephone conversations were not relied on as evidence.
20.  The applicant's subsequent appeal on points of law was rejected by the Supreme Court (Hoge Raad) on 18 February 1997.
21.  In so far as is relevant to the case before the Court, the applicant complained under inter alia Article 8 of the Convention that the Court of Appeal had wrongly rejected his argument that the prosecution should be declared inadmissible or that evidence had been unlawfully obtained in respect of the recordings made of his telephone conversations with Mrs S. The Supreme Court dismissed this complaint in the following terms:
 “6.2.2. It is ... correctly assumed in the grounds of appeal on points of law that no interference by any public authority is permitted in the exercise of the right to 'respect for his private life and his correspondence' guaranteed by Article 8 § 1 of the Convention unless, and to the extent, provided for by law. 6.3.1. What is decisive in the instant case is therefore the answer to the question whether, noting the part played by the police in the recording of the telephone conversations that S. has had with the suspect, there has been an interference by the police in the exercise of the right of the accused to 'respect for his private life and his correspondence'. 6.3.2. Against the background of the facts and circumstances ... the finding of the Court of Appeal that the police has not acted in such a directive manner – in which finding the Court of Appeal apparently had in mind the entire part played by the police in the recording of the telephone conversations by S. – that there has been an interference by any public authority within the meaning of Article 8 § 2 of the Convention is not incomprehensible, and furthermore it does not reflect an incorrect understanding of the law, in particular, not as regards the contents of that provision of the Convention ... 
After all, [the case] concerns in essence a (female) victim of a sexual offence, this woman not having any other prima facie evidence than her own account and to whom the police has given information about a possibility for her to obtain additional proof and to whom and to this end the police has subsequently provided practical (technical) aid for performing certain acts – the recording, in her own home and in the absence of the police and with the aid of a device connected by the police to her own telephone line, of an incoming telephone conversation which the perpetrator conducts with her –, which act does not, for that woman, she being a party to the telephone conversation recorded, constitute an act prohibited by law.
Nor does the finding that the circumstance that the suspect in his capacity of practising lawyer has a 'privileged status' is not relevant in this matter reflect an incorrect understanding of the law. On the above grounds, the Court of Appeal could conclude that this was not a situation referred to in Article 125g of the Code of Criminal Procedure. The findings of the Court of Appeal are sufficiently reasoned.”
